Abstract: Based on the policy and standard requirements of industrial robot application programming skill level certificate, combined with the analysis and deconstruction of domestic industry status and professional post ability requirements, this paper reconstructs the professional curriculum system from several aspects such as professional core curriculum, professional curriculum and professional development curriculum, and integrates the examination content of certificate training into professional curriculum to form a curriculum system composed of two coherent main lines. The contents of the course are connected, supplemented, expanded and promoted. The constructed curriculum system fully integrates the training and assessment content of 1 + X vocational skill level certificate, which lays a certain foundation for the assessment and certification of subsequent certificates, and has a certain reference for the curriculum setting of talent training program of industrial robot specialty in higher vocational colleges.

1. Introduction In January 2019, the State Council issued the “Implementation Plan for National Vocational

Education Reform”, which proposed to “promote the construction of qualification framework, and explore the interconnection between academic certificates and vocational skill level certificates. And deepen the reform of the training mode of compound technical and technical talents, and start the pilot work of 1+X certificate system “[1]. Students are encouraged to obtain various vocational skill level certificates while obtaining academic certificates. As an important reform and deployment of “20 vocational education”, the 1+X certificate system is also a major transformation and upgrading. Industrial robot application programming was selected as the second batch of pilots, and the Ministry of Education issued the Notice on Doing a Good Job in the Second Batch of 1+X Certificate System Pilots in September 2019 (J.S.H. [2019] No.89). It is required to integrate the 1+X certificate system into professional talents training, reconstruct the curriculum system, optimize the teaching content, coordinate the teaching organization and implementation, and deepen the reform of teaching methods and methods according to the “1+X” vocational skill level standard, combining the professional talents training scheme with the vocational skills training assessment module. This is an important way to improve the quality of personnel training, and an exploration of building a national qualification framework.

According to the spirit requirements of the document “Pilot Program for Implementing the System of” Academic Certificate+Several Vocational Skills Level Certificates “in Colleges and Universities”, colleges, industries and enterprises will unite, and reflect new technologies, new processes, new specifications and new requirements according to national professional standards and international and domestic advanced standards, and combine the contents of “1+X” vocational skills level certificates for industrial robots with courses to meet the talent training standards [2]

For this reason, this paper takes the industrial robot technology major in ordinary higher vocational colleges as an example, and interprets the content of “1+X” in combination with the tasks in the work field of the industrial robot major. According to the professional skill level standard of industrial robot application programming, after the job task structure, the curriculum system of industrial robot technology specialty is reconstructed from three aspects of knowledge,

ability and quality training requirements, and the method and path to realize the integration of courses and certificates are explored to improve the quality of professional talents training.

2. Job Analysis of Industrial Robot Industry (1) Industry analysis Robots are known as “the pearl at the top of the manufacturing crown”, and their R&D,

manufacturing and application levels are an important symbol to measure the developed degree of a country's high-end manufacturing industry, and an important entry point to realize and promote National Industry 4.0, Made in China 2025 and Robot Industry Development Plan (2016-2020) [3]. With the development of China's industrial robot industry, the country has successively issued policies related to manufacturing industry, and constructed the top-level industrial design from a macro and strategic perspective. The “intelligent” development of robot products has been strongly supported by the state, and the driving role of robot technology in industrial transformation and upgrading has become increasingly prominent.

In 2018, the national level successively introduced the guidance and support ideas for the industrial robot industry, paying more attention to the improvement of the overall management level and industrial level, so as to support the corresponding measures such as the reduction of capital, the VAT rate, the strengthening of brand quality, the revision of industrial standards, and the protection of intellectual property rights. The healthy development of China's industrial robot industry has been encouraged and standardized [4].

It is predicted that the growth period of China's industrial robot industry will enter a high-speed state in the next five years, which belongs to the rapid development stage of R&D, manufacturing and application enterprises of Chaoyang industrial robot industry in China [4].

Fig.1 Life Cycle of the Industrial Robot Industry

Industrial robot industry is divided into upstream, midstream and downstream according to industrial chain. It is specifically divided into upstream enterprises that produce reducer, servo system and controller core components; Mid-stream manufacturing enterprises composed of ontology manufacturers; Downstream application enterprises composed of single system integrators and integrated system integrators [4]. Due to the serious lack of core components in China, the cost of industrial robots in China is raised and the development of the industry is restricted. The industrial robot industry is mainly concentrated in ontology and integration.

In addition to the automobile, 3C, metal processing, injection molding and other industries where robots are mainly used at present, the demand of many long tail industries is growing, such as medicine, food, logistics, chemical industry, petrochemical and so on. According to the demand growth rate of downstream industries from 2018 to 2020, the growth rate of food and medicine, logistics and semiconductor is in the forefront.

(2) Analysis of industrial posts According to the analysis of industrial robot industry development trend, industrial chain and

application industry. With the application and development of industrial robots in industrial robot body manufacturing, industrial robot system integration, industrial robot generation and application, and industrial robot sales, there is still a lack of applied talents in enterprises, such as on-site debugging, maintenance operation and operation management. This requires more engineers and technicians, and requires employees to master the technologies of industrial robot operation, maintenance, debugging, troubleshooting level system integration and so on. According to the forecast in the Planning Guide of Manufacturing Talent Development, the talent gap in the field of robots and high-grade CNC machine tools will reach 4.5 million by 2025 [5]. According to the needs of the industry, we have obtained the main positions, tasks and professional abilities of students majoring in industrial robot technology in higher vocational colleges.

Fig.3 Curriculum System Before the Course Certificate Connection

2.1 + X Certificate Connotation and Professional Orientation (1) Connotation of 1 + X certificate 1+X certificate is the vocational skill level certificate of vocational college graduates and social

workers, which reflects the comprehensive ability needed by professional activities and personal career development [6]. In the 1+X certificate system, “1” is an academic certificate, which is basic and subjective, and is the main body of vocational higher vocational education, based on the realization of all-round development of moral, intellectual, physical, aesthetic and labor training and professional technical skills education. “X” is a number of vocational skill level certificates under the certificate system developed by enterprises, which not only has quantitative requirements, but also provides specific quantitative quality indicators for the quality of personnel training. It requires pertinence, guidance and advancement for the ability training of vocational posts, and it is the enhancement, supplement or expansion of vocational skills, professional qualities or new technologies and new skills of talents in higher vocational personnel training. As the proof of the learning experience and learning situation of the educated, the academic certificate is mainly to train high-quality workers and technical and technical talents to meet the needs of industrial economic and social development. The vocational skill certificate is a proof of the professional knowledge and skill level possessed by the certificate winner, which focuses on cultivating talents with high-level technical skills, and has both commonness and particularity [7]. 1+X certificate system is based on the value of “1” to promote the status of “x”, which is an upgrade of the academic certificate system, that is, on the basis of obtaining academic certificates, students are encouraged to obtain various vocational skill level certificates. Academic education and vocational skill level training complement each other. The former is the foundation, while the latter is to upgrade vocational skills and promote the reform of academic education and teaching [8].
